| 1. A computer apparatus, which is connected with a navigation apparatus to be mounted on a mobile unit through a communication
network so that the computer apparatus enables to communicate with the navigation apparatus, comprising:
a recommended-route generating section that calculates a recommended route between two arbitrary points based on a recommended-route
generation algorithm to generate recommended-route information;
a route search information transmitting section that transmits route search information including the recommended-route information
to the navigation apparatus;
a first receiving section that receives a notice of completion of reception for the route search information transmitted from
the navigation apparatus;
a second receiving section that receives guidance result information including traveling route information of the mobile unit
which moves based on the recommended-route information; and
a learning section that conducts a learning process by modifying the recommended-route generation algorithm based on the recommended-route
information and the traveling route information.
